The black kite, whistling kite, and brown falcon are known for using this phenomenon to catch prey. This phenomenon (15[1])triggers the flowering of Telopea speciosissima, the waratah. Though not involving heavy machinery, this phenomenon causes a large decrease in soil porosity; it also (15[1])increases the concentrations of the nutrients potassium, magnesium, and calcium and thus increases soil pH. Adapting to this phenomenon is the primary function of (*) epicormic buds and lignotubers. This phenomenon causes certain tree species, such as the lodgepole pine, to release seeds (-5[1])in the process of (10[2])serotiny. (10[1])This phenomenon is the most typical natural cause (10[1])of secondary succession. Eucalyptus trees are themselves resistant to this phenomenon while containing oils that promote this phenomenon. For 10 points, name this phenomenon that often starts when dry brush is hit by lightning. ■END■ (10[1])
